Why Molecular Sieve Powder are used for Coatings, Adhesives, Sealants and Elastomers?

Molecular sieves are synthetically manufactured crystalline, porous structures. They absorb moisture and water from substances to dry the substances completely. The most common component used in these sieves is zeolites. They offer protection against moisture and water. Moisture is the foe of many coatings, sealants, adhesives, and elastomers. It can come from pigments, fillers or ambient air during the production period. Moisture causes damage and spoilage of these products. Isocyanides react with moisture in polyurethane-based formulations. Here CO2 generation can cause problems like blistering and degradation.
